' meme-sonnet.-

To all whom it may concern:

Be it known that I, HADEN HERBERT' BALEs, a subject of the King ofEngland, re-

siding at Ashcroft, in the county of Yale,

Province of British Columbia, Canada, have ments in Packin -Sc rews, ofwhich the following is a speci cati ont his invention relates to toolsand more particularly to packing tools, and'has for its object toprovide a tool with which packing may be removed from or inserted in thestuffing boxes of pumps, engines and similar structures with facilityand which will also simple and cheap.

Other objects and advantages will be apparent from the followingdescription and it wlll be understood that changes in the spe cificstructure shown and described may be made within the scope of the claimswithout de arting from the spirit of the invention.

11 the drawings forming a portion of this specification and in whichlike numerals of reference indicate similar parts in the several views,Figure 1 is an elevational view show ing the manner of using the presentpacking, tool. Fig. 2 is an elevational view of one form of the tool,Fig. 3 is a similar view showing a second form of tool, Fig. 4 is a toolshown in Fig. 3, Fig. 5 isan elcvational view-of a third form of tool,Fig. 6 is a longitudinal section through the form of tool shown in Fig.5.

e erring now more particularly to the there is shown in Fig. 2 a-packingtool com rising a packing engaging screw 10, lie form of a cork screw,and carried y a stem section 11, which is connected by means of auniversal joint 12, with a stem section 13 carrying a handle 14. Theuniversal joint 12 comprises two 0 positely disposed yokes 15, receivinga bloc 16 between their arms, and to which block the arms-are pivoted.vIt will thus be seen that the sec-- tion 13 of the stem may be turnedlaterall with respect to the section 11, and that by osition the section11 may be rotated t rough rotation of the handle 14.

Thehandle may thus be moved out of positlon to engage the piston rod ofapump', or other portions of the structure which might interfere withits 0 eration.

In Fig. 3 of the rawings, there is shown a form of packing toolincludinga stem 17 hav ing a handle 18 at one end, and havin itsopposite end threaded and engaged in a Specification of Letters rarest.application filed June 30, 1908.

- socket 27 Patented April :27, 1909. Serial No. 441,147.

frusto conica l block 19, this block being threaded on its outersurface. A stiff helical s ring 21 has its helices engaged with thetli-read 20 of the block 19, and has engaged in its 0 posite end, asimilar exteriorly threaded bloc 22, having a longitudinally extendingangular socket 23 opening through its outer end, for the rece tion ofthe angular shank 24 of a bit 25,- w 'ic'h may either be a screw bit asshown in the drawings or a stuffing bit for replacing packing. The bitis held with its shank in the socket by means of a set screw 26 engagedin the block 22. The bit may thus be removed for replacement when brokenor when changes are desired.

In Fig. 5, there is shown a packing tool consisting of a helical spring25', having a block 26 engaged in one end, provided with a or thereception of a bit 28', this block being equipped with a'set screw 28 tohold the bit in the socket. A chain 30 1s attached at one end to theblock 26, and passes through-the sprin 25. In the opposite end of the sring mm the block 26,

there is engaged t e reduced portion 32, of

a block 32 having a longitudinal passage 33 formed therethrough andreceiving the stem 34 of a hook 35, this hook having the chain 30engaged t *erewith. The stem 34' of the hook extends outwardly beyondthe block 32, and is threaded for the reception ofa nut 36', which maybe operated to draw the stem of the hook through the passage 33, tintsvarying the distance between the two blocks 26 and 32,-and adjusting thetension of the spring 25. A handle yoke 37 has its ends secured in theblock 32, at opposite sldes of the opening of the passage 33, and this.hand e yoke may be gras ed for operatlo'n of the packing tool. It wi Ibe observed that the springs 21 and 25 movement of the grip ends of thetool w1th res ect to the packing engaging ends, the two on s of the toolbeing thus universally connccted.

In some cases, when old or hard packing has to be removed from astufiing box, the o erator may find it necessary to pull upon tlEehandle 37 with block and tackle, and in this case, the chain 30 takesthe extra straln at is claimed is: 1. Azpacking tool having a springportion be 'een its ends arranged for movement of the end portions ofthe tool out of ahnement wit each other, said spring portion beingangvplrevents undue distortion of the spring.

also arranged to hold the end portions normally in a ement with eachother.-

2. A packing engaging tool including handle consisting in 3. A packingtoo comprising a hehcal spring, a packing engaging member connected witone end of the spring and a handle connected with the other end of thespring.

4. A blocks engaged in the ends of the s ring, a handle connected withone of sai blocks and a packing engagin member connected with the otherof said blocks 5. A acking tool comprising a helical spring, locksengaged in the ends of the s ring, a handle connected with one of said bocks, and a acking engaging member connected with the other block. i

6. A acking tool comprising a helical spring, locks engaged in the endsof said s ring, flexible connections between the b ocks, a handlecarried by one of said blocks, iIlld. I: packing member carried by theother 7. A packing tool comprising a helical spring, a block engagedwithin the helical rin and a packing member carried by e b ock.

8. A packing tool comprising a helical spring, a block engaged withinone end of the hehcal spring, a block enga ed within the other end ofthe spring, sai second block havin a passage formed 'therethrough, athrea ed stem slidably engaged in the passage, a set nut engaged withthe stem outi wardly of the passage, a chain connected 1 with the stemand with the first named block,

and a packing member carried by one of the blocks.

5 sisting in part of a helical spring, art of a helical spring. 1 forvarying the tension of the spring.

i packing member carried by one packing tool comprising a spring, i

i ing lOqln a packing tool, the combination 1 with a packing elementincluding a stock conof means 11. A packing tool comprising a spring, aen of the spring, a handle carried by the o posite end o the spring, andmeans for varying the tension of the s ring.

12. A pac ing tool comprising a spring, a packing member removabconnected with i one endof the sprin ,ahand emembercarried l by theopposite en of the spring, and means i for varying the tension of thespring, said means being slidably connected with the end of the springto which the packing member is l connected, and slidably connected withthe 1 end of the spring to which the handle memher is connected.

1 13. A tool com rising a handle including end portions, a he icalspring connected with the end portions and extending therebetween, saidspring being arranged for movement of the end portions laterally wlthre- I spect to each other and toward and away from each other, and meansfor limiting the movement of the end portions awayfromeach 1 other tohold said end ortions with the spring under tension, said imiting meansheing arranged for lateral movementof the end portions with respect toeach other.

14. A packing tool including a handle con- 5 sisting of two endportions, a helical spring i engaged at its ends with the end portions,and a chain connected with an end to each of the end portions of thehandle and lying within the helical spring, and means for movthe chainwith respect to one of the end l portions to vary the tension of thespring.

In testimony whereof I afiix my signature,

9. A packing tool comprising a helical in presence of two witnesses.
